One of my rescues, rex, has some swelling in both his rear legs from about the fetlock down. We just have begun a refeeding program for him because he is so underweight. He gets 2 cups sweet feed 3 cups of omolene 400 (foal grain reccomended by our vet for him) and some alfalfa cubes all soaked and mixed together. He is not stalled and has free run of the pasture so i'm not sure what could be causing him to stock up. Also, hes unbroke and to weak to excersize so I'm unable to reduce the swelling that way. Is the swelling something I should worry about? Perhaps I should change something in his diet or will it just go away? thanks!
